Meaning – The term reassembly, refers to the process of putting segmented packets back together after they have been received. Segmentation and reassembly (SAR) is the process used to fragment and reassemble variable-length packets into fixed-length cells so as to allow them to be transported across asynchronous transfer mode (ATM) networks or other cell-based infrastructures.
The process is conceptually simple: an incoming packet from another protocol to be transmitted across the ATM network is chopped up into segments that fit into 48-byte chunks carried as ATM cell payloads. At the far end, these chunks are fitted back together to reconstitute the original packet.
The term reassemble, also refers to the process of repairing a computer in order to fix an issue with the hardware.
Example of usage – “Computer repair is a broad field encompassing many tools, techniques and procedures used to repair computer hardware, software or network/Internet problems.”
